The common screening methods for biosurfactants are presented Sampling and isolation of bacteria are the basis for screening of biosurfactant producing microbes Hydrocarbon contaminated sites are the most promising for the isolation of biosurfactant producing microbes but many strains have also been isolated from undisturbed sites.
The terms biosurfactant and bioemulsifier have often been used interchangeably to describe surface active biomolecules However it is important to note that there are marked differences between them especially based on their physico chemical properties and physiological roles Although bioemulsifiers and biosurfactants are both amphiphilic in nature and are produced
Biosurfactants are surface active compounds from biological sources usually extracellular produced by bacteria yeast or fungi.Research on biological surfactant production has grown significantly due to the advantages they present over synthetic compounds such as biodegradability low toxicity diversity of applications and functionality under extreme conditions.
The recent outbreak in severe acute respiratory syndrome coronavirus 2 SARS CoV 2 has demonstrated the complete inability of nations across the world to cope with the pressures of a global pandemic especially one in which the only current feasible treatments are those which deal with the symptoms alone and not the viral cause As the death toll rises scientists begin to fall

Diabetic eye screening DES Published on 13 April 2022 Diabetic retinoaphy is an eye condition that occurs when high blood sugar levels damage the cells in the retina Blood vessels in the retina can leak or become blocked This condition may cause blindness or serious damage to eyesight making screening important.
Clinical documents endorsed by ASCCP are considered official ASCCP clinical guidance In general ASCCP endorses documents that are developed with ASCCP's participation from the beginning of document development Support of a peer organization's clinical document denotes that ASCCP deems the document to be of educational value to its
Aug 15 2018 REC17.1 Screening in DES exposed women Women exposed to DES in utero should be offered an annual co test and colposcopic examination of both the cervix and vagina indefinitely Consensus based recommendation REC17.2 Colposcopy referral for abnormalities in DES exposed women.
Dec 27 2011 Biosurfactant production was screened in four lactobacilli strains The highest biosurfactant production excreted and cell bound biosurfactants was achieved with Lactobacillus paracasei ssp paracasei A20 a strain isolated from a Portuguese dairy plant with a decrease in the surface tension of 6.4 mN m −1 and

Aug 24 2021 This document describes the programme specific operating model PSOM for quality assurance QA of the NHS diabetic eye screening DES programme.This PSOM was developed by a working group led by
the production of biosurfactants and contains all necessary substances lactose protein organic acids and vitamins that require for growth of surfactant producing microorganism This study focus on the screening production extraction and purification of biosurfactant from bacteria isolated from whey spilled soil and which
tested for lipid content of biosurfactants has significant advantages over traditional methods All biosurfactants gave the positive results with sulfo phospho vanillin reaction This means all biosurfactants obtained in this study have a lipid content The functional groups of biosurfactants were confirmed by FT IR spectra Figure 2 .
Screening for biosurfactants among crude oil degrading marine microorganisms from the North sea z Naturforsch C 46 4 197 203 Saruboo L.A 2006 Production and Stability studies of the Bioemulsifier obtained from a strain of Candida
Biosurfactants are surface active compound that reduce the interfacial tension between two liquids or that between a liquid and a solid Their unique property like nontoxic easily biodegradable eco friendly and high stability and wide variety of industrial application makes them highly useful group of chemical compound.
Jun 01 2017 Currently screening of microbial biosurfactants BSs is based on their equilibrium surface tension values obtained using static surface tension measurement However a good surfactant should not only have a low equilibrium surface tension but its dynamic surface tension DST should also decrease rapidly with time
